Electric Switches TRIZ Cases

Inclined walls in a rubber dome generate two-stage tactile feedback, reducing noise and extending key travel distance.

Actuation delay circuit detects rectified voltage ripple peaks to time relay switching at zero-crossings, reducing inrush current and extending lifespan.

Early break auxiliary contacts open before standard power contacts to interrupt the inverter drive control circuit and prevent stray surge current damage.

Current source control circuit drives contactor coils using a delay mechanism to switch from pull-in to hold current.

Pressing super-aligned carbon nanotubes onto substrates creates uniform conductive layers, resolving ITO durability and transparency trade-offs.

A circuit breaker uses silicon carbide semiconductor switching elements to redirect current flow through a secondary path during operation.

An electromagnetic relay uses an integrated alignment part on the insulating wall to constrain movable armature travel.
